Specification forming part of Letters Patent No. 183,020, dated October10, 1876 application filed August 12, 1576.

To all whom it may concern:

Be it known that I, HIRAM S. POMEROY, of the city and county of NewHaven, and State of Connecticut, have invented a new and usefulImprovement in Sash-Pulleys; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and useit, reference being had to the accompanying drawing, which forms a partof this specification.

My invention relates to sash-pulleys; and consists in a novel device foroiling the pivots of the pulley without removal, which is hereinaftermore fully set forth and definitely claimed.

Figure l is a view of the front or face plate of the case and of theprojecting portion of the pulley. Fig. 2 is a View of that portion ofthe case which is inserted in the window-frame.

The pulley-casc is made in three partsthe face-plate A, and-the twoflanges m m. The face-plate has the usual slot in the central part, andthe usual screw-holes near its ends. It has projections 01. a, to whichthe flanges m m are attached. From the central part of the upper end ofthe face-plate a groove, 0, running each side of the screw-hole extendsdown the face-plate and over the projection a. A hole or notch, 0,through the face-plate connects with the groove, as shown in thedrawing. The flanges m m are made in the usual form, and have theordinary pivot-holes, the upper parts inclosing the pulley. A projectionor guiding-rib, b, on each of the flanges extends upward from thepivot-hole to and under the groove 0 made in the face-plate, as shown inthe drawing. The pulley has its face grooved and is cast in one piecewith pivots.

The pulley being thus constructed, the oil inserted through the hole 0runs down the groove 0 onto the rib b, and down the same to the pivotsof the pulley.

I claim as my invention A sash-pulley whose face-plate A is providedwith the groove 0 and notch c, and whose flanges are provided with theguidingribs 11 b, substantially as described and shown, for the purposeset forth.
